Adriatic Metals PLC (ASX:ADT, LON:ADT1) ("Adriatic" or the "Company") is pleased to provide the following Quarterly Activities Report ("QAR") that summarises the progress made and reported during the three months ended 30 June 2020 ("Q2" or the "Quarter").

Paul Cronin, Adriatic's Managing Director and CEO commented,

"Despite the challenges of the global COVID-19 crisis, the company has made substantial progress during the quarter, advancing our exploration program and continuing to deliver on our permitting and organisational developments. Our staff in both Bosnia and the UK, have demonstrated a stoic determination to deliver on operational objectives and add shareholder value, but simultaneously assist our local community to manage the challenges laid down by an extraordinary health emergency.

Our announced acquisition of Tethyan Resource Corp is the first phase of implementing a strategy to identify and acquire substantially accretive assets to our portfolio of high value, high margin assets. The diversification that these assets bring, leverages our core strengths internally to realise value growth and progress Adriatic on its journey to being a UK based, European focused, multi-asset mining company. We look forward to completing the transaction in the coming weeks, and adding Tethyan's outstanding team, to the Adriatic family."

1. COVID 19 IMPACT

Adriatic commenced a 20,000m drilling campaign for 2020 in mid January, ramping up the rig count recently to 5 rigs. Border closures in the Balkans had forced the Company to reduce the rig count to 4 temporarily, but this was increased back to 5 rigs in early June. Adriatic applied for, and received, an exemption from the curfews imposed during March to May and managed to maintain the drilling program, albeit at a slower pace than originally planned. Some delays have been experienced with assay results, but again this is now returning to pre-COVID delivery timeframes. All other exploration activity is continuing unaffected, with supplies being delivered on time.

In 2020 to date we have drilled over 7,500 m with 25 holes completed, and have recently permitted a further drill pads for an increase in exploration activity over the coming months.

All activities related to metallurgical test work, geo-chemical domaining and pre-feasibility assessment are underway and largely unaffected by the current crisis. For the Environmental and Social Impact Assessment, where some foreign based consultants had been expected to conduct site visits for various streams of work, these have been substituted by local resources under the guidance of our international consultants, with no resulting impact on the quality of work.

As a result of the expansion in the mineralised footprint visually evident from recent drilling, a deferral of the Pre-Feasibility Study ("PFS") was considered to allow additional drilling to be incorporated into an updated mineral resource estimate, which will be utilised for the PFS. This is not as a result of any delays in PFS work streams, which are all progressing as planned, or any COVID-19 related issues. The PFS is now expected to be complete in September 2020.

In December a public hearing was held for the issue of the Environmental Permit which resulted in a small number of additional information requests from the Federal Ministry for Environment and Tourism. The company submitted responses in late January and the Ministry issued the permit in May. Whilst the total timeframe to complete the process was longer than originally planned, we appreciated the efforts of the Ministry to progress our application in a difficult period for the Bosnian government. The Company has submitted the Urban Planning Application and are currently working with the Federal Ministry of Spatial Planning to progress the application to final approval.

As of 25 July 2020 Bosnia, & Herzegovina has approximately 9500 confirmed cases of COVID-19, and whilst relatively small when compared to other European countries, a recent increase in new cases may result in further restrictions of movement of people. The Company has robust measures and contingency plans if such restrictions are imposed.

2. PRE-FEASIBILITY STUDY ("PFS") PROGRESS

Nine further Lock Cycle Tests are in progress by Wardell Armstrong in the UK, specifically to test both grade and mineral variability across the Rupice deposit. The results of this test work are being reviewed as received and incorporated into the mine planning and process flow sheet assumptions. Results of the test work will be incorporated into the PFS and released in September.

Drilling remains underway to convert inferred resources into indicated for the purpose of the PFS, and this drilling is expected to be complete in mid-August 2020. Expansion drilling will continue at Rupice, Jurasevac Brestic and Borovica during the next quarter.

The PFS commenced in late January and is being led by Ausenco who have suggest several options for process optimisation from the initial Scoping Study assumptions. Trade-off studies commissioned as part of the PFS are now complete. Data is also being collated and reviewed so that an updated Mineral Resource Estimate ("MRE") incorporating the latest drilling results and geological interpretation, can be completed.

The mining team's review of the Scoping Study has identified optimised mining methods in several areas and detailed mine planning and scheduling is now being developed which will be finalised following completion of the updated MRE.

Detailed logistics studies are also complete as part of the PFS, reviewing in-country as well as international shipping of products and incoming reagents and materials. Infrastructure requirements for the project have also been determined and trade off studies have now identified several areas of optimisation.

Concurrently with the PFS, the international ESIA baseline data collection has continued this quarter using Wardell Armstrong as lead consultants and utilising considerable in-country resources and skills. The baseline data collection will continue until Q1 2021 leading to the final stages of the ESIA and the final report issued in Q2 2021. There are regular meetings between the PFS and ESIA teams to ensure complete alignment of all project needs.

3. EXPLORATION

The Company completed 4,976m of drilling in the Quarter, and received permits for additional drill pads in anticipation of further exploration activity during the coming months. Assay results were received during the Quarter and include the following significant results:

· Drill hole BR-02-20 intercepted mineralisation along strike to the south of Rupice extending the known area of mineralisation 20m down dip returning 8.9m @ 2.40g/t Au, 398g/t Ag, 1.79% Zn, 3.16% Pb, 0.35% Cu and 45% BaSO4 from 368.5m

· Drill holes BR-06-20, BR-07-20 and BR-09-20 confirm continuity of the high-grade mineralisation in the central part of the Rupice deposit:

· BR-06-20 - 26.7m @ 3.95g/t Au, 502g/t Ag, 6.75% Zn, 3.76% Pb, 0.35% Cu and 72% BaSO4 from 275.5m

· BR-06-20 - 10.2m @ 5.81g/t Au, 876g/t Ag, 8.65% Zn, 5.94% Pb, 0.50% Cu and 69% BaSO4 from 323m

· BR-07-20 - 9.3m @ 3.49g/t Au, 393g/t Ag, 3.13% Zn, 3.86% Pb, 0.36% Cu and 59% BaSO4 from 181.7m

· BR-07-20 - 22.9m @ 3.18g/t Au, 259g/t Ag, 10.71% Zn, 6.48% Pb, 0.63% Cu and 45% BaSO4 from 199m

· BR-09-20 - 31m @ 3.85g/t Au, 335g/t Ag, 9.50% Zn, 8.12% Pb, 0.76% Cu and 36% BaSO4 from 198m.

Recent drilling at Rupice has been focussed on converting inferred resources into the indicated category for the upcoming revised Mineral Resource Estimate, following the successful expansion of the resource outline

Analysis of historical exploration data, augmented with a significant program of surface sampling and geo physics has resulted in the company responding to a Public Invitation issued by Zenica-Doboj Canton for a new concession agreement, which will cover a significant portion of the known Triassic mineral belt to the North West, South and South East of the town of Vares, totalling 32.12 km2. The Public Invitation application period closed on 23 July 2020, with Adriatic being the only applicant. The Company is now working on agreeing the terms of a new Concession Agreement with the Canton. Further details of the Concession Agreement will be provided when finalised in August 2020.

4. ACQUISITION OF TETHYAN RESOURCE CORP

On 11 May 2020 Adriatic and Tethyan Resource Corp. (TSX-V:TETH) ("Tethyan") announced that they have entered into a binding Letter Agreement and subsequently on 12 June 2020 a Definitive Arrangement Agreement whereby Adriatic will acquire 100% of the outstanding common shares of Tethyan, by way of a plan of arrangement under the Business Corporations Act (British Columbia), in consideration for the issuance of 0.166 of an ordinary share of Adriatic for each common share of Tethyan outstanding at the effective time of the arrangement.

In conjunction with the transaction, Adriatic and Tethyan have entered into a convertible loan agreement, whereby Adriatic has advanced to Tethyan a secured convertible loan in the amount of up to €1.3 million in three tranches. The loan enables Tethyan to close the transaction for the acquisition of EFPP d.o.o., the holder of parts of the Kizevak and Sastavci deposits, to commence confirmation drilling at Kizevak, and to meet the expenses and costs of Tethyan in completing the transaction

The acquisition will result in the addition of Tethyan's Serbian brownfield development projects, Kizevak and Sastavci, and its large prospective landholding on the Tethyan mineral belt and positions the enlarged Adriatic as the leading Balkan base and precious metals developer. Adriatic plans to rapidly advance the past-producing Kizevak and Sastavci polymetallic mines in the Raska district of southwestern Serbia towards a maiden JORC compliant resource by end-Q4 2020

Tethyan shareholders will gain exposure to Adriatic's existing exploration and development portfolio including the exceptional Vares Project and prospective regional exploration potential in Bosnia & Herzegovina

The Tethyan Board of Directors unanimously supports the Transaction and irrevocable undertakings to vote in favour of the Transaction have been received from approximately 55% of Tethyan shareholders. The Transaction is expected to close by end-August once all conditions have been met

The Arrangement is subject to customary conditions, including receipt of requisite shareholder, court and stock exchange approvals and the listing of the Adriatic Shares to be issued thereunder on the London Stock Exchange. The parties currently expect the Arrangement to be completed in or about August 2020. Upon completion of the Arrangement, Tethyan will apply to delist the Tethyan Shares from the TSX Venture Exchange.
